This separator filters those contaminants before they re-enter the engine.\u003c\/p\u003e\n\u003ch3\u003eDoes this vent to the atmosphere like other catch cans?\u003c\/h3\u003e\n\u003cp\u003eNo—this is a closed-loop system. Oil and vapors collect in the canister instead of venting to the air, keeping oil off your bike and the ground.\u003c\/p\u003e\n\u003ch3\u003eHow often do I need to empty or service it?\u003c\/h3\u003e\n\u003cp\u003eThe two-piece design unscrews for easy cleaning. Service interval depends on riding conditions and engine wear—check monthly and empty as needed.\u003c\/p\u003e\n\u003ch3\u003eWill this work with my S\u0026amp;E air cleaner?\u003c\/h3\u003e\n\u003cp\u003eYes—this separator is designed for both stock and S\u0026amp;E air cleaner configurations on M8 engines.\u003c\/p\u003e","brand":"Moroso","offers":[{"title":"Default Title","offer_id":53035871535215,"sku":"82-9506","price":362.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/ce4f-62056219ae02c_53526992-436a-4a83-9005-957cc3395046.jpg?v=1777529910","url":"https:\/\/vtwinbikers.com\/products\/moroso-air-oil-separator-m8-w-stock-and-se-air-cleaners-polished-82-9506","provider":"Vtwinbikers","version":"1.0","type":"link"}
